Introduction:
Every great idea starts in the brain, so why not 3D model the idea itself? This project dives into transforming raw brain scan data into a tangible 3D print. It’s about turning thought into form, where anatomy meets artistry, and curiosity becomes something you can actually hold. A friend of mine reached out with an unusual request; his boss wanted to 3D print a brain from his friend’s MRI scan. In my experience, nothing in 3D modeling has felt truly impossible, just speed bumps that require creative workarounds. Most roadblocks usually come down to time and money. Is there a deadline? What’s the budget? With that in mind, I was all in, ready to tackle the project and adapt my 3D modeling workflow to bring this idea to life.
Project Overview:
I love turning people’s ideas into tangible reality, especially when the original idea starts growing into different projects, which often happens as I explain to the customer all of the possibilities with 3D modeling. I’m also mindful not to overload the customer with answers that might confuse them, so I stick to the point and offer additional info that’s relevant. Since the original project was simply to find out if 3D printing a brain was possible, I skipped unnecessary back-and-forth and asked, “What’s the end goal you have in mind?” The short answer was that it would be a surprise gift for his friend. That helped focus the direction, though these days, the definition of a gift can be just about anything.
Step 1: Prepping the Brain Scan
Most 3D modeling projects start with gathering reference images, building an inspiration board, and collecting all important files before modeling in ZBrush. In this case, I received an MRI scan in .dicom format, which ZBrush can’t read. So the first step was finding compatible software. After some deep diving on Google, testing multiple softwares, and watching tutorial videos, I was able to properly convert and import the scan into ZBrush.

Step 2: Cleaning and Preparing for Print
With the brain model in ZBrush, the next step was making it 3D print-friendly. Every scan file comes with cleanup work like removing artifacts and smoothing out rough areas.
Things to consider included:
1) Final size of the 3D print
2) Detail level of gyri and sulci (those brain wrinkles)
3) Printer bed limits and whether to split the brain into parts
4) Detachable or permanently fused parts
5) Other print limitations discovered along the way
Step 3: Testing and Feedback
Refinements and new ideas usually come after holding the first prototype. I printed a small, computer-mouse-sized brain and another full-scale version. One was hand-painted brain-pink by a miniatures painter friend, and the other was spray-painted candy pink. To avoid back-and-forth on subjective preferences like color, I showed the customer color swatches. It’s always smart to request visual references early on to avoid miscommunication.
Step 4: Wrapping Up and Moving Forward
The prototype was a success, and everyone was happy with the print options. But I felt the idea wasn’t fully finished. I revisited the project and expanded it into a full brain scan package that I now offer to body scan clinics and individuals who have access to their brain scan data.
Key Takeaways:
Albert Einstein once said, “Once you stop learning, you start dying.” I think that goes for ideas too. They deserve a shot at becoming real. I get all kinds of wild 3D modeling requests, figure out what’s doable, and after sending my quote for the project and getting approved, I get to work bringing that idea into the real world!
